Head rather compressed, snout rounded, very prominent. Rostral 
large, forming a broad suture with the prefrontals ; nasal small, on 
the side of the rostral (in the two specimens in the Collection, 
this plate has fused with the rostral, but this should be considered 
rather as anomalous, since four other specimens examined by Strauch 
are said to have the nasal completely separated from the rostral) ; 
a pair of large preefrontals, followed by a pair of smaller frontals 
forming together a heart-shaped figure ; eye not, distinct through the 
ocular: three upper labials, anterior smallest; mental subquadran- 
gular, followed by a pentagonal chin-shield; three lower labials, 
anterior very small, second largest ; a large chin-shield on each side, 
behind the second labial. Two hundred and twenty-two or two 
hundred and twenty-six annuli on the body, and sixteen or seyen- 
teen on the tail; on the middle of the body an annulus contains 
thirty-eight segments, twenty above and eighteen below the lateral 
lines ; the dorsal segments longer than broad, the two median 
ventrals a little broader than long. Lateral lines distinct. Anal 
segments eight or ten; preanal pores four. Brownish white, each 
dorsal segment with a small central brown spot.
